I'm going to say no; that sounds like an extra option we could add later.
More details on that API:
* Our current API: Either fit the intercept, or fix it at 0. Do not
regularize it if fitting.
* "bias" API in liblinear: Fit the intercept, but adjust regularization by
adjusting "bias."
* My issues with this:
* It's not intuitive (if I understand their API correctly). To avoid
regularizing the intercept, you set the "bias" to be large.
* R glmnet uses our current API (fit intercept or don't), and it seems
like a more authoritative codebase to follow.
Later on, I could imagine us adding the option to regularize the intercept.
